Help black slime mold

[MikeyD]

Does anyone know how to get rid of black slime mold? It's in my wife's 20 gallon and I'm tired of looking at it.

You are probably referring to cyanobacteria. It's cause by excessive nutrients in the tank. You can get rid of it by improving the water quality. Feed less, do water changes more often, make sure you are using RO/DI water for water changes and top offs and run a high quality carbon.
